26 !!DESCRIPTION
27
28
29 ''Uuencode'' and ''uudecode'' are used to transmit
2 StuartYeates 30 [Binary] files over transmission mediums that do not support
31 other than simple [ASCII] data.

33
34 ''Uuencode'' reads ''file'' (or by default the
35 standard input) and writes an encoded version to the
36 standard output. The encoding uses only printing ASCII
37 characters and includes the mode of the file and the operand
38 ''name'' for use by ''uudecode.'' If ''name'' is
39 ''/dev/stdout'' the result will be written to standard
40 output. By default the standard UU encoding format will be
41 used. If the option ''-m'' is given on the command line
42 __base64__ encoding is used instead.
43
44
45 ''Uudecode'' transforms uuencoded ''files'' (or by
46 default, the standard input) into the original form. The
47 resulting file is named ''name'' (or ''outfile'' if
48 the -o option is given) and will have the mode of the
49 original file except that setuid and execute bits are not
50 retained. If ''outfile'' or ''name'' is /dev/stdout
51 the result will be written to standard output.
52 ''Uudecode'' ignores any leading and trailing lines. The
53 program can automatically decide which of the both supported
54 encoding schemes are used.
55 !!EXAMPLES
56
57
58 The following example packages up a source tree, compresses
59 it, uuencodes it and mails it to a user on another system.
60 When ''uudecode'' is run on the target system, the file
61 ``src_tree.tar.Z'' will be created which may then be
62 uncompressed and extracted into the original
63 tree.

72 !!STANDARDS
73
74
75 This implementation is compliant with
76 P1003.2b/D11.
77 !!BUGS
78
79
80 If more than one file is given to ''uudecode'' and the -o
81 option is given or more than one ''name'' in the encoded
82 files are the same the result is probably not what is
83 expected.
84
85
86 The encoded form of the file is expanded by 37% for UU
87 encoding and by 35% for base64 encoding (3 bytes become 4
88 plus control information).
